Deep geologic repository progress—2025 Update
Editor's note: This article has was originally published in November 2023. It has been updated with new information as of June 2025.
Outside my office, there is a display case filled with rock samples from all over the world. It contains a disk of translucent, orange salt from the Waste Isolation Pilot Plant near Carlsbad, N.M.; a core of white-and-bronze gneiss from the site of the future deep geologic repository in Eurajoki, Finland; several angular chunks of fine-grained, gray claystone from the underground research laboratory at Bure, France; and a piece of coarse-grained granite from the underground research tunnel in Daejeon, South Korea.

The Cryogenic Forevacuum System (CFV) of the JET Active Gas Handling System is designed to collect gas mixtures from the torus and injection systems. The CFV separates hydrogen isotope mixtures from helium and impurities and stores isotope mixtures for separation. All crucial process elements are located in all-metal secondary containments. Prototype tests on accumulation panels have shown the capability of pumping hydrogen/helium/impurity mixtures. A pumping speed of 12500 ℓs-1 has been measured for deuterium with mass flow rates up to 125 mb ℓs-1. Cryotransfer pumps were shown to pump typical batches of 100 ℓ (STP) H2 or D2 in 15 minutes.
